The screw 26 is simply backed ed a sufficient distance to permit rotative adjustment of the stop member l3 with the coacting stop in some definitely adjustedposition, When the correct adjustment of the stop I3 for one spindle has been made relatively to one coacting stop 12, the screw 25 is tightened up and the machine indexed to bring the corresponding stop l3 of the next spin dle into position to be engaged by the same coacting stop I 2. I 'he stop I3 of the latter spindle is ithen'adiusted in the same manner and so on for ;th e ;others;'. The stops 13 would be adiustedin i the samemanner, and all of the spindles would therefore have the stops so set that, in effect, any

7 small diiferences in what may be'termed the radii of the spindles, that is, the distance from the axis of the spindle carrier, would be compensated for and identicfal piece parts would thus be produced. 1 7 With forming slide stops of .the'character'dis closed, whereina special. type of driver or wrench is required for adjustment, it is unlikely'that'op eratorswould' ever tamper with the adjustments of .thejstops, which: adjustments, of course, when 7 oncepropefly made are permanent.
